* feat(web): add workspace browser for multi-directory navigation Add /browse route with a folder browser that lets users navigate filesystem directories on connected machines and launch sessions from any folder. Supports saved workspace paths and direct path input. The "Start Session" action pre-fills the NewSession form. - CLI: register machine-level `list-directory` RPC handler - Hub: add POST /machines/:id/list-directory route - Web: add WorkspaceBrowser component with git repo detection - Web: add /browse route with navigation from sessions sidebar - Web: support initialDirectory/initialMachineId in NewSession Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com> * feat: add --workspace-root opt-in scoping for /browse and session spawn Adds a single new flag, \`--workspace-root <path>\` (with \`~\` / \`~/foo\` expansion), on \`hapi runner start\` and \`hapi runner start-sync\`. When set: - The runner reports the path in machine metadata. - The list-directory and spawn-session RPC handlers reject paths outside the root, so the web UI can't escape the configured tree even if someone crafts a request manually. - The /browse page in the web UI auto-opens that root, restricts the breadcrumb / go-up to its subtree, and shows directory entries with git-repo annotations. - The /sessions/new form keeps its existing free-text directory input plus autocomplete + recent-paths chips, and gains a small "Browse" button (next to the input) that opens /browse for picking a folder. - Reconnect-time metadata sync ensures stale records get the field filled in (or cleared when the flag is dropped on a later restart), so the hub state matches the CLI's intent. When unset: - Runner behaves like the legacy hapi (no scoping, no browse feature). - /browse renders an informative state pointing at the flag instead of blocking the user. - The /sessions/new form looks identical to the pre-change behavior; the "Browse" button is hidden. Includes a startup banner so \`runner start-sync\` no longer looks like it hung, and surfaces the workspace-root sync result on stdout. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(hub): preserve workspaceRoot when rehydrating machines from store MachineCache.refreshMachine() rebuilt the metadata object from an explicit field allowlist, so any field not in the list (including the new workspaceRoot) was silently dropped on every read — even though it was correctly written to the store. Add workspaceRoot to the zod schema, the Machine interface, and the hand-rolled projection. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * feat(web): friendlier empty state on /sessions When there are zero sessions the page used to be a vast blank rectangle with just the "0 sessions in 0 projects" caption. Render a centered empty state instead: a calendar/agenda icon, a short heading and hint, and two buttons — "Start a session" (→ /sessions/new) and "Browse workspace" (→ /browse). SessionList gains an optional onBrowse prop. Router wires it on the sessions page so the secondary button resolves; other callers can leave it unset to hide that button. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * docs: document --workspace-root flag in cli/README and root README Add a short paragraph under "Runner management" in cli/README.md explaining what \`--workspace-root\` enables (scoped /browse tree, list/spawn enforcement, tilde expansion) and that omitting it keeps the legacy behavior. Mention the workspace browser in the top-level README's Features list. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix: address PR #526 review feedback Three findings from the review bot: 1. [Major] Workspace-scope check was lexical only. With workspaceRoot = /safe, a symlink such as /safe/out -> /etc would pass the relative- path test and let list-directory / spawn-happy-session reach paths outside the configured root. realpath the workspaceRoot at construction time, and resolve every incoming path through realpath (walking up to the nearest existing parent for spawn targets that haven't been created yet) before the containment check. 2. [Minor] \`hapi runner start --workspace-root\` with no value used to drop the flag silently and start the runner unscoped. Now treats a missing or flag-shaped next argument as an error. 3. [Minor] /sessions/new's "Browse" button always opened /browse using localStorage's last-used machine, ignoring the user's current selection. NewSession already passes machineId in its callback; forward it through the /browse search params and seed WorkspaceBrowser with it. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com> * fix(cli): gate list-directory RPC behind --workspace-root opt-in Without a configured workspaceRoot, isWithinWorkspaceRoot() returns true unconditionally, leaving the new list-directory RPC able to enumerate any path on the runner. The Web UI already hides Browse for these machines, but the backend should enforce the opt-in too. Refuse the RPC up front when no workspace root is configured. --------- Co-authored-by: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

hapi hub
hapi server remains supported as an alias.
If you only need web + CLI, you can omit TELEGRAM_BOT_TOKEN.
To enable Telegram, set TELEGRAM_BOT_TOKEN and HAPI_PUBLIC_URL, start the hub, open /app
in the bot chat, and bind the Mini App with CLI_API_TOKEN:<namespace> when prompted.

Security model
Access is controlled by:
- Telegram initData verification plus bound Telegram users (bound via
CLI_API_TOKEN:<namespace>). CLI_API_TOKENbase secret for CLI and browser access (namespace is appended by clients).
Transport security depends on HTTPS in front of the hub.
Build for deployment
From the repo root:
bun run build:hub
bun run build:web
The hub build output is hub/dist/index.js, and the web assets are in web/dist.
Networking notes
- Telegram Mini Apps require HTTPS and a public URL. If the hub has no public IP, use Cloudflare Tunnel or Tailscale and set
HAPI_PUBLIC_URLto the HTTPS endpoint. - If the web app is hosted on a different origin, set
CORS_ORIGINS(orHAPI_PUBLIC_URL) to include that static host origin.
Standalone web hosting
The web UI can be hosted separately from the hub (for example on GitHub Pages or Cloudflare Pages):
- Build and deploy
web/distfrom the repo root. - Set
CORS_ORIGINS(orHAPI_PUBLIC_URL) to the static host origin. - Open the static site, click the Hub button on the login screen, and enter the hapi hub origin.
Leaving the hub override empty preserves the default same-origin behavior when the hub serves the web assets directly.
